Standard Bank - No Respect for Deceased Customers

Standard Bank Vehicle Finance division customer service is atrocious!! I have now spent almost 3 hours on hold trying to get through to the department that deals with deceased estates. My Mum passed away in February and we are simply trying to obtain a log book for a paid up vehicle that she owned. I have spoken to a few call centre agents who keep giving me the same number to call - this number does not get ANY response at all. My longest wait time on hold has been 90 minutes. I have emailed the addresses provided by Standard bank and one has an auto response asking for another email to be sent to a different address. Copies of death certificates and all the associated documents were sent to this address too. Any auto response was received but a month later I am still trying to get ANY response at all from Standard Bank.
